Ode to Craig's List (and equivalents)

Oh Craig's List you save us dough
When back and forth to new homes we go
We sell and buy and sell and buy
And now we have a new dresser high!
Our white changing table is gone
Our crib buyer was not a con
Our treadmill has run away
But a new bunk bed has come to stay!
With some pieces removed, and others to add
We understand that "bartering" is more than just a fad.
No richer now, nor poorer we know
The kids' room is transformed...how fast they grow!
